The deputy provost at Aberdeen City Council has accepted the role of MSP.
Tom Mason will replace Ross Thomson, who became the MP for Aberdeen South at last week’s general election.
Mr Mason, who represents Midstocket and Rosemount at the council, will be sworn in as an MSP for the North East list seat on Tuesday and will continue in his role at the council.
However, his councillor salary will be donated to charity.
Mr Mason said: “I am honoured to have been offered the list seat for the North East region.
“Ross Thomson was a champion for the North-east in his role as an MSP and I will strive to do my very best for the people of this area.”
